Mutated Mobs
Ever thought vanilla mobs were a bit... boring? Yeah, me too. This mod adds mutated versions of Minecraft mobs - bigger, meaner, and way more fun to fight (or run away from, no judgement).

The Lurker
A tall horror mob that lurks in the Overworld. Very rare spawn. You'll hear him before you see him.
Stats:
- 150 HP
- One-hit kill attack (no, seriously)
- Full knockback resistance
- Slow but relentless
Behavior:
- Chases players on sight. Slow, but smart.
- When he gets close enough and can see you, he freezes you in place and kills you. No escape.
- After chasing you for 10 seconds, he starts a Hide and Seek game.
- He announces "Let's play Hide and Seek!", counts down from 60, and then comes looking for you.
- If he finds you (line of sight + close range), it's Game Over. He teleports in front of you and sprints at you full speed.
- At 30 seconds left in the search, he teleports 10 blocks ahead of you regardless. Game Over.
- You actually need to break line of sight and hide behind walls. He can't trigger Game Over if he can't see you.
Spawning:
- Very rare in the Overworld
- Comes with a spawn egg
Tips:
- Build walls. Seriously.
- Don't try to outrun him during the sprint phase, he has Speed V.
- During the countdown phase, get as far away as possible and hide behind solid blocks.
